Anyone have other any > suggestions as to diagnosing of fixing the problem? Are there any DPMS options set in your xorg.conf ? What is your video card/monitor and what driver are you using in X ? Another thing to check is see if DPMS is enabled as an extension by your setup: xdpyinfo |grep DPMS should return "DPMS" I have to explicitly set my monitor power saving to off on my laptop otherwise the screen has a high likelyhood of not coming back on after turning off. Toshiba says it's a known behavioral issue with multi core laptops. Happened under XP as well. Yay for screen burn in. nate
